The CSS for both Ask Ubuntu and Ask Ubuntu Meta contains a useless CSS value. (When I say useless, I mean that it doesn't affect the page at all if removed.)
As you can see, the
.container for the page contains the CSS style
position: relative; and I have no idea why because none of the other StackExchange sites have that property set.
The reason it needs to be removed is because it's breaking at least two of my UserScripts that absolutely position content on the page.
